Holly Willoughby nailed the minimal make-up look last night

The big, bouffant blow-dry has felt dated for a few years now. However, it's safe to say that most of us still struggle to create that effortless, just-got-out-of-bed look without looking like we actually have just got out of bed and not brushed our hair. Last night, Marion Cotillard pulled off the hairstyle with Parisian chic.

Why it works: While Cotillard has a tousled, undone finish, there is not one ounce of frizz. The key to pulling off undone hair is to make sure the texture of your hair is smooth and shiny.
